I have installed the 302 from a 79 thunderbird in my "66. Sorry no choice it was missing the motor. I need your advice on the 3 pulleys to allowa one belt system to run the water pump and alternator. It has the 4 bolt hole crankshaft mounting. I'm not opposed to serpentine if that's the way to go. No A/C, no power steering.

 

Check out March for a pulley set. You could also find a 2-groove crank pulley to go with a 1-groove water pump pulley.

You can also hit the wrecking yards, I think they switched to the 4-bolt balancer in '70

 

Junk yard items. The only issue is the radiator needs to have the lower hose barb relocated to the drivers side to match the water pump. The radiator shop can do this for you

In this photo. What year and engine did the crank and waterpump pulleys come from? I have the radiator switched and have all the other parts.
